Looks like the 1D X's faux manual mode is exactly the same as the 1D Mark IV. There is a minimum shutter speed you can set in the main menu, however, the fastest in that menu is 1/250s.

If ISO Safety Shift, Min shutter speed to 1/500 or 1/1000, with auto ISO and EC set to whatever you wish. I would have liked if you can set Min shutter to 1/640 or 1/800. I can't remember if you can on the 1D4 but I don't think you could; I think it jumped from 1/500 to 1/1000 if I remember correctly.

The 1D4 goes 1/60, 1/125, 1/250, 1/500, 1/1000, 1/2000 as well

I am very happy with that - most of the time I use 1/250 or 1/500 by default.

I am happy with it too, but you know how it is, when you get something new you maybe hope it may do the 1/3 stops of 1/640 and 1/800

It is only a minimum - so in bright light I am often much faster

Dont forget you can dial in min/max ISO too - again full stops. My 1D4 is set for L/6400

Another alternative is to set the Safety shift to TV/AV and shoot on TV

In Tv mode, the Tv/Av Safety Shift behaves the same way only changing the shutter speed instead. For a required exposure of f/1.4 at 1/250th with a lens that can only open up to f/2.8, Safety Shift would cause the camera to drop the shutter speed to 1/60th to insure a proper exposure. Alternatively, an exposure that required an aperture smaller than the lens could produce would result in shortening the shutter speed until the exposure was correct. With Autoiso set then this only shifts when the ISO limit is reached.
